Written in easy to follow language, the book presents cutting-edge agriculturally relevant plant biotechnologies and applications in a manner that is accessible to all. This book introduces the scope and method of plant biotechnologies and molecular breeding within the context of environmental analysis and assessment, a diminishing supply of productive arable land, scarce water resources and climate change. Authors who have studied how agro ecosystems have changed during the first decade and a half of commercial deployment review effects and stress needs that must be considered to make these tools sustainable.
The management of major vitreoretinal diseases has changed dramatically since publication of the first edition in 1999. The field continues to evolve rapidly and is becoming an increasingly complex, multifaceted practice of medicine and surgery. As such, retinal specialists are faced with increasingly sophisticated diagnostic and therapeutic modalities to learn and master. Contributors to this completely updated reference are renowned experts in retinal disease and vitreous disorders. Divided into four essential sections, the book starts with a basic overview of posterior segment anatomy and physiology. The second section reviews the spectrum of diagnostic tools used in the field from relatively low technology such as the indirect ophthalmoscope to the latest, state-of-the-art optical coherence tomography test. The third and most comprehensive section covers disease states, subdivided into eight categories: retinovascular conditions, macular diseases, inherited vitreoretinal conditions, inflammatory conditions, intraocular tumors, vitreous and retinal detachments, trauma and toxicity, and fundus conditions. The text concludes with specific vitreoretinal procedures. Key Features New technologies including spectral domain optical coherence tomography (OCT), intravitreal injections, and microincisional vitrectomy The utilization of multifocal electroretinography, scanning laser ophthalmoscopy, and fundus autofluorescence Advances in treatment of macular edema and age-related macular degeneration with anti-VEGF therapy Summaries of the latest and most important clinical trials Richly illustrated with more than 700 color state-of-the art retinal images and surgical procedure drawings Clinical pearls, controversies, and special considerations highlighted in color boxes in every chapter This up-to-date, clinically-oriented resource will greatly benefit ophthalmology residents and ophthalmologists with comprehensive practices.
The eastern screech owl, widespread over the eastern half of North America and noticeably tolerant of human activity, is one of America's most familiar birds. Residing naturally in wooded environs with tree cavities, this owl lives well in suburbia and can be found nesting in mailboxes, porch columns, and purple martin houses. Based on a twenty-five-year study, biologist Frederick R. Gehlbach tells the life story of the eastern screech owl, focusing on case studies of suburban and rural study plots in Central Texas. This is the first thorough study of major life-history, behavioral, and ecological features of the species. Indeed, it is the first concurrent, comparative study of an urban and a rural population of any New World animal. Told in a personal voice, the story of these birds will interest all who have not lost touch with their ancestral world. However, Gehlbach has also included quantitative data and analysis of interest to ecologists, wildlife biologists, and ornithologists. Photographs (including color shots of the gray and rufous phases), figures, and tables provide further detail. Gehlbach's investigations have been those of not only an academic ecologist, but a suburbanite curious about his natural surroundings. The result is a model of research on species population dynamics and adaptation, yielding an emerging picture of what the eastern screech owl needs for successful coexistence with human neighbors.
A Time Best YA Book of All Time (2021) In this “searing work of historical fiction” (Booklist), Coretta Scott King Award-winning author Sharon M. Draper tells the epic story of a young girl torn from her African village, sold into slavery, and stripped of everything she has ever known—except hope. Amari's life was once perfect. Engaged to the handsomest man in her tribe, adored by her family, and fortunate enough to live in a beautiful village, it never occurred to her that it could all be taken away in an instant. But that was what happened when her village was invaded by slave traders. Her family was brutally murdered as she was dragged away to a slave ship and sent to be sold in the Carolinas. There she was bought by a plantation owner and given to his son as a "birthday present". Now, survival is all Amari can dream about. As she struggles to hold on to her memories, she also begins to learn English and make friends with a white indentured servant named Molly. When an opportunity to escape presents itself, Amari and Molly seize it, fleeing South to the Spanish colony in Florida at Fort Mose. Along the way, their strength is tested like never before as they struggle against hunger, cold, wild animals, hurricanes, and people eager to turn them in for reward money. The hope of a new life is all that keeps them going, but Florida feels so far away and sometimes Amari wonders how far hopes and dreams can really take her.

Well appointed with photos, line illustrations, and schematics, Clovis Revisited is essential reading for professionals, students, and avocational enthusiasts.
With their unique maneuverability, drones and flying robots are used for all kinds of work. Drones can save lives in disasters. They fly over and photograph disaster-stricken areas so relief workers can find those who most need help. Drones can also be a farmer's best friend—they help farmers check on crops from the sky, saving them time, money, and a whole lot of work. Discover more fascinating facts about drones and flying robots—from who first invented them to how we'll use them in the future—in this up-close look at cutting-edge technology!
SOCIAL PSYCHOLOGY AND HUMAN NATURE, 4th Edition, offers a remarkably fresh and compelling exploration of the fascinating field of social psychology. Respected researchers, teachers, and authors Roy Baumeister and Brad Bushman give students integrated and accessible insight into the ways that nature, the social environment, and culture interact to influence social behavior. While giving essential insight to the power of situations, the text's contemporary approach also emphasizes the role of human nature -- viewing people as highly complex, exquisitely designed, and variously inclined cultural animals who respond to myriad situations. With strong visual appeal, an engaging writing style, and the best of classic and current research, SOCIAL PSYCHOLOGY AND HUMAN NATURE helps students make sense of the sometimes baffling -- but always interesting -- diversity of human behavior.
